Question 1. What is the relationship between t and F if both are performed for a two-group test?
ANOVA will have the lower rate of type I error.
t = F
t will have less error variance.
t2 = F
Question 2. The number of sets of measures that a within-subjects F will accommodate is ___________.
one
two
two or more
three or more
Question 3. The within-subjects F is the non-independent groups equivalent of the one-way ANOVA.
True
False
Question 4. Repeated measures designs reduce error variance as long as the scores are correlated.
True
False
Question 5. The equivalent in the F ratio of SEd in the t ratio is _______.
MSwith
SSwith
MSbet
SSbet
Question 6. Post-hoc tests identify the location of significant differences in an ANOVA.
True
False
Question 7. The independent variable in either a before/after t or a within subjects F is always of what data scale?
Nominal
Ordinal
Interval
Ratio
Question 8. The test statistic in ANOVA is which ratio?
Error variance divided by variance within groups
Between groups variance divided by error variance
Total variability divided by error variance
Error variance divided by between groups variance
Question 9. What is the highest value eta-square can have?
There is no upper limit.
1.0
.5
.25
Question 10. If a one-way ANOVA and a within-subjects F were calculated for the same set of data, how would the SStot values compare?
SStot for the one-way ANOVA would be larger.
The SStot values would be the same for each test.
The SStot for the one-way ANOVA would be smaller.
The SStot for the within-subjects F would contain a larger portion of error.
